Warships The history of warships goes back in history to the ancient Greeks and Romans. Their ships were called galleys. The galleys were powered by oarsmen. The galley had a sharp point in the front for ramming other ships.

In the A.D. 700's, the Vikings invented the long ship. It weighed less than the galley and was stronger and more seaworthy. The Viking's controlled the seas until the 1000's.
